Yesterday, Donald Trump made the too little, too late move of firing Attorney General Jeff Sessions after Special Counsel Robert Mueller had by all accounts already reached the finish line of his investigation. The question was why the usually-tepid Trump pulled the trigger at all. Now there’s suddenly buzz everywhere that Donald Trump Jr is on the verge of arrest. This is bolstered by the fact that one of the people making this assertion is Junior himself.

Donald Trump Jr has been running around telling people that he thinks he’s going to get indicted soon, according to New York Magazine and Politico. But this report is just the start of it. Now the Democratic Coalition has just announced that according to its sources, Junior’s arrest is “imminent.” Other usually-reliable pundits are floating the same thing. But really, this comes back to Junior’s own claim that he’s about to get popped – and yes, there are ways he could know it’s about to happen.

For instance, Robert Mueller’s people told Paul Manafort in advance that he was about to be indicted and arrested, in the hope of convincing him to cut a plea deal. It’s not quite as clear why Mueller would give Donald Trump Jr an advance heads-up, as he’s not going to flip on his father, at least not right away. That said, if Mueller has hauled Junior’s associates before a grand jury, they could have tipped him off about how far Mueller has progressed.

There are a couple key things to keep in mind here. We don’t know if Robert Mueller is planning to nail Donald Trump Jr for Trump-Russia collusion right out of the gate, or if he might initially have someone like SDNY nail Junior on more-easily-proven financial crimes instead. If Mueller hands it off, that would help circumvent any potential complications raised by Jeff Sessions’ recent firing. Also, if Junior is about to be arrested, it would mean he’s already been indicted, and it’s under seal. Stay tuned.
